The yieldable arms 33 formed from the material cut out to form the 40 are preferably twisted out of the plane of the slots 2-2 in the socket illustrated in Figs. 1 base I (Fig. 2) so that they provide an elongated through 4.

Thus it is only necessary my invention is best defined by the following to provide a thin slit (Fig. 3) in the material beclaims. tween the slots 2-2 to form the stud-receiving I claim:

aperture 4. The aperture 4 is made into the 1. A snap fastener socket having abase, a pair 55 of yieldable arms having both their ends connected to said base and being twisted to an angle of less than ninety degrees relative to the plane of said base and said arms having free outer edges and being spaced apart along their inner edges to provide a stud-receiving aperture between them and a slot between each of the arms and the base to permit a torsional action of said arms throughout their length for yielding action away from each other to permit enlargement of the stud-receiving aperture when a stud is forced between the arms, and attaching prongs formed integral with said base and extending therefrom in the opposite direction from the yieldable arms.

2. A fastener socket formed from a single piece of sheet metal and having a base portion, a pair of yieldable arms having both their ends connected to said base portion and being twisted to an angle of less than 90 relative to the plane of said base portion, said arms having free outer edges and being spaced apart along their inner edges to provide a stud-receiving aperture between them, which aperture is larger in width adjacent to the middle of the arms than adjacent to where the arms join the base portion for reception of a fastener stud by a direct movement oithe socket toward the stud, and said socket having oppositely positioned slots each of which is between an arm and the base portion to permit torsional action of said arms for enlargement of the stud-receiving aperture particularly adjacent to the widest portion.
